Figure out the average monthly rent for that unit, take out 35-40% in expenses, then subtract out debt and that's your cash flow.Then calculate the total cash flow annually for that property and plug in your downpay cash in and initial rehab done if any and you will get your cash on cash roi. 

Excluding my high end rentals, my average purchase is about $40K, and average rent is $900.

Hi All BP-ers,My name is Jacob and I am currently doing research on making propertymanagement/investing more fun, productive and profitable.As a PM/Investor/Agent what are the biggest problems you face on a day-to-day basis?

You can finance improvements and labor after work has been accomplished, earned equities from products or services like some window company finances new windows after they are installed, this is a contractor financing arrangement.

Adding a small loan (like the "credit builder" loan some credit unions offer) will just decrease the average age of your accounts, which is the last thing you want.The same with new credit cards.What will help is increasing limits on pre-existing cards.

Gon't exagerate.I remember one guy that came to me with a decent plan, decent numbers, sufficient assets and a decent product, but he didn't get a dime from me.....why?

We average 1k in turnover with lost rents and make ready costs, so retention is priority 1.

I am an agent and also an investor, whenever I put the finished product on the market I always disclose that I am an agent, if the house is priced right and if you did a good job on the rehab you do not need to worry about them trying to negotiate, you will probably end with a multiple offers anyway

Throw in the below average credit and collections...

I'm curious as to how much on average do you spend on a rehab; Not including holding costs and other fees, just the fixing and labor it self.
